STRAND OR CORD WORKING MACHINE.

Application filed December 31, 1923.

To all whom it may concern:

Be it known that I, CLARENCE GRIFFITH S'roLL, a citizen of the UnitedStates, residing at Oak Park, in the county of Cook and State ofIllinois, have invented certain new and useful Improvements in Strand orCord Working Machines, of which the following is a full, clear, concise,andexact description.

This invention relates to strand or cord working machines, and moreparticularly to a machine for binding a plurality of strand materialstogether.

An object of this invention is to provide a machine which will beeflicient in operation and so compact in structure as to substantiallyincrease the productive capacity of the floor space occupied by themachine.

A further objectof this invention is to provide a machine so designedthat the strand is drawn from the strand supplies and through the strandworking devices and stored on the take-up devices with a minimum amountof bending thereof and with no deleterious friction or wear thereon.

In its preferred form the invention consists of a single unitary frameupon two opposite sides of which is mounted a pair of independentlyoperable strand working de vices. Associated with each strand workingdevice is a pair of strand supplies arranged therebelow, side by sideupon the same side of the frame and at an angle whereby the feed of thestrand therefrom is focused on a guide positioned below the strandworking devices. Mounted above and on a line intermediate the devicesand each pair of strand supplies is a pair ofconcentric capstans ofcomparatively large size, one for each of the strand working devices,whereby the strand is subjected to a minimum amount of bending. Thecapstans operate in opposite directions to draw the pair of strands fromeach of the associated strand working devices and direct the workedstrands to suitable guides and then to a storage device disposed belowthe strand working devices and upon that side of the machine upon whichthe strand supply for the opposite strand working device is positioned.Means, re-

sponsive to the tension on the strand material traveling from thecapstans to the associated storage devices, is also provided forregulating the speed of the aforementioned storage devices and therebymaintaining a substantially constant tension on the strand between thesaid capstans and strand storage devices.

It will be apparent, however, that the features of this invention arereadily applicable to other mechanisms and are not limited to their usewith the apparatus disclosed.

Other objects and advantages of the invention will more fully appearfrom the following detailed description taken in connection with theaccompanying drawings, in which Fig. 1 is a front view of the machine;

Fig. 2 is a view taken from the left-hand side of Fig. 1;

Fig. 3 is an enlarged vertical detail sectional view taken through thesupply spool mechanism Fig. 4 is an enlarged vertical sectional viewtaken on the line H of Fig. 3 looking in the direction indicated by thearrows, and

Fig. 5 is an enlarged vertical sectional view of the capstan mechanism.

Referring now to the drawings in detail in which like reference numeralsdesignate similar parts throughout the several views, 10 is a machineframe on which is mounted four complete binding units, two on each sideof the frame. Each binding unit comprises four sub-units, a supply spoolunit 11, a serving or binding unit 12, a capstan unit 13, and a take-upspool unit 14. These sub-units are mounted independently of each otherin such a way that any one can be removed without disturbing the others.

Suitably located in the lower part of the frame 10 is a motor 15 whichdrives all four units through the medium of one main or common shaft andsuitable intermediate gearing (not shown).

As shown in Fig. 2 the wires 16 are fed from the underside of the supplyspools 17 and 18 to a guide 19 located in binding sub ell) ' whereasunit 12. The spools 17 and 18 are mounted at an angle with their headsadjacent, on a rotatable member 21, (Fig. 3) thereby enabling the strandmaterials to be withdrawn therefrom with a minimum amount of friction,the feeding angle of the strand materials being focused on the guide 19(Figs. .1 and .c.%eeured to a stud which is suitably attached to thelower part of the frame 19, is a stu l 28 upon which the member 21rotates. Located on top oi? the rotatable member 21 is a small cam lever25 pivotally secured to a loci-t pin 26, which extends through therotatable member 21. As best shown in Fig. A the rotatable member 21 islocked against rotation through the engagement of the end of the lockpin. 26 in an opening 2'! in the stud Formed around the lower part ofthe lock pin 26 is a small collar 28 which lits snugly in an enlargedopening 29 in the rotatable member 21. Between the collar 28 and upperpart of the opening 29 is a small compression spring 30, which upon theoperation of cam lever to loci; the rotatable member 21 causes the lockpin to be forced into its locked posi ion. By unlocking the member 21and rotating it and the spools attached thereto on the stud 22 theoperator enabled to expeditiously unload and reload the strand spoolcarrying member 21.

A chain 32 (Fig. 13), which is attached at one end to a l 33, passesover a grooved pulley which is mounted in a bracket secured to the frene. lhe other end of the chain 2 which passes over pulley 3 1, isattached to a. weight 36. A small length of chain passes over thegrooved pulley 3 1 being secured at one end to a handle 38.

t1 e other end is also secured to the weight 36. The r ight 36 causesthe chain to be drawn taut, drawing up the lever 32 which in turn causesa lever saaft '1 to turn. The lever sha'tt l1. which is meanted at oneend in a support -2 in turn operates a series of levers. which causes ashoe l?) to be pressed against the material on the supply spool therebypreventing the material from overrunning the spool and also tending tomaintain a constant tension on the strand being withdrawn. By drawthehandle 38 and placing it. in :1 -11 n'ionnted on the frame 10 the 1 33drops of its own weight, causing the shoe 43 to also drop.

The wires 16 to be bound together are ravn from the supply spools 17 and18 irough the guide 19, serving head 45, cop magazine brackets -l-6 andcops a? by a power driven capstan 18 located in the capstan unit 13.

As shown in Fig. 5, capstan unit 13 consists of two concentric capstans18 and 19 of the same diameter, having interlocking flanges androtatable in opposite directions.

The capstan bearing housing 50 in which the capstan mechanism is locatedis secured to the frame 10. Keyed to the end of a vertical shaft 51 is abevel gear which is meshed with a bevel gear 53. l he bevel gear 53 issecured to a capstan shaft sleeve 5% by a key 55. Keyed to the verticalshaft 51$ is a bevel gear 5? which is meshed with a bevel gear The bevelgear 58 is secured to a capstan shatt 59 by a key 60. t eparating thetwo bevel gears 5-8 and 53 is a shoulder (31 on the capstan shaft 59 andtwo thrust collars 62 and 63. The capstan shaft 59 revolves in thecapstan shaft sleeve Bl and bearing (31, while the capstan shaft sleeverevolves around the capsl an shaft 59 and in the bearing 65.

Located on the capstan shaft sleeve H are two thrust washers (58 and 69.A thrust washer 1 0 on the capstan shaft 59 separates the hubs of thecapstais 4:9 and 4L8. The capstan 1? is secured to the capstan shaftsleeve by hey 71 and the capstan 4:8 is secured. to the capstan shaft 59by a key 7 2. Two lock nuts 73 and '71 on the end of the capstan shaft59 retain the two capstans 18 and :19 in their respective positions.Located throughout. the capstan bearing housing 50 are oil feeds, suchas 75, T6 hnd 7. A thrust washer T8 fits around the capstan shaft 59 andbetween the housing 50 and the bevel gear 58. The vertical shafts 51 and56 revolve in the bushings (36 and G7 and the bearings 79 and 80.

Suitably located in each unit is a tension assembly 81 which isresponsive to the tension on the strand material traveling from thecapstan sub-unit 13 to the take-up spoo s.d -unit Iii: and adapted tothereby 1 i (e the speed o the said take-up spool sub-unit ll, thusn'eventing any undue ten- Sic-n upon the strand.

A lever 86 operates a disc clutch (not shown)associated with the driving mechanism of one complete unit. By operatingthis lever the mechanism of that particular unit can be stopped withoutinterfering with the other three units.

The machine above described, having a pair of independently operablestrand work ing devices upon two opposite sides there of with a pair ofcomparatively large diameter capstans for each pair of devices arrangedconcentrically thereabove for drawing the worked strand therethroughpro- 'vides a machine which has great productive capacity for the floorspace occupied thereby. The concentric mounting of the capstans reducesthe floor space occupied by the machine compared to a similar machinehaving each capstan mounted upon a separate shaft where the capstans areof the same diameter in both instances. Also due to the comparativelylarge diameter capstans and the angular mounting of the strand suppliesbelow the strand working devices for focus ing the strands upon theguide positioned below the strand working devices, the strand is drawnthrough the strand working devices and around the capstans and stored onthe take-up reel with a minimum bending thereof, and with no deleteriousfriction or wear thereon.
